Former Scotland midfielder Eoin Jess has joined Peterborough as first-team coach.
Jess, who had two spells with Aberdeen during his playing career but also spent time in English football with Coventry, Bradford, Nottingham Forest and Northampton, as well as winning 18 internationals caps, has agreed a three-year deal at London Road.
The 41-year-old replaces Mark Robson, who left the npower Championship club in June to become Barnet's head coach.
"I have been very patient and quite meticulous in getting the right one in. After doing my research on him, it became apparent that his philosophies are exactly the same as ours and that was the most important thing," boss Darren Ferguson told the club's official website.
Gavin Strachan, son of former Coventry, Southampton, Celtic and Middlesbrough manager Gordon, had been working as acting first-team coach but will now revert to his normal role of youth team manager.
Ferguson added: "It is no slight on Gavin Strachan, in fact it is a compliment to him that I want him to remain with the youth team because I see that as a such an important role in getting players through."
